Chaotic dynamics of resistively coupled DC-driven distinct Josephson junctions and the effects of circuit parameters. (English) Zbl 1188.94052
The paper is concerned with the study of a rich dynamical behavior of a resistively coupled Josephson junction device. Contrary to previous studies where an AC source has been used, the authors consider a coupled non-identical junction circuit driven by a DC source. It is established that oscillations of the voltage \(V\) and phase difference \(\theta\) strongly depend on the source currents and junction capacitances. The authors conclude that the dynamical behavior of the device can be efficiently controlled through the source currents, whereas junction capacitances can be used as additional control parameters.
